Specfication of Letters Patent.

Patented Dec. 3, 1907.

Application filed May ll. 1907. Serial No. 373.072.

T 0 all 'whom it may concerns Be it known that I DANIEL H. SHILLABER, a citizen of the United States, residing at Lynn, in the county of EsseX and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Soles, of which the following is`a specification.

My invention relates to an improvement in soles for boots and shoes, and the method of making the same, it being an object of the present invention to utilize a portion of the sole leather which is ordinarily covered by the heel, to form the bottom lift of a heel, subsequently filling the orifice or cavity thus formed and covering it over With a portion of the sole leather Whereby a valuable portion of the sole which would otherwise be covered by the heel is utilized as a part of the heel itself, making the lower surface of the heel of the same quality of leather as the sole without the necessity of cutting these heel lifts from a separate piece of leather, and thereby materially economizing in the initial cost or manufacture `without in any wise impairing the commercial value of the shoe itself.

l/Vith the foregoing object in View, my present invention consists in splitting the heel endof the sole blank for a suitable distance, then cutting a heel lift from the thicker portion of the split end of the sole, filling the cavity thus formed and subsequently covering it over with the integral lip split from the sole.

The invention further consists in certain novel features of Construction, and combinations of parts, which will be hereinafter described and pointed out in the claims.

In the accompanying drawingsz-Figure 1 is a plan view of the sole showing the lip split therefrom partly raised. Fig. 2 is a bottom plan view. Fig. 3 is a longitudinal sectional view. Fig. 4 is a sectional view through the modification. Fig. 5 is a sectional view showing a thin piece of material pasted or otherwise secured over the heel portion.

A, represents the sole blank as Originally cutfrom the hide. This sole is split through the heel portion and part way to the center, preferably on the flesh side, leaving relatively thick and thin portions, the latter of which will be termed the lip 1, which is left integral along the line 2, 2, with the sole blank. After splitting, the heel lift 3 is cut from the heel portion by a' suitable die and this heel lift 3 becomes a commercial article just like the sole, to be used as the bottom t ticular sole from which it is cut, although the quality of these heel lifts when thus formed are the same as the soles. After the heel lift is thus formed, the cavity 4 left remaining may be filled with inferior material, of any suitable kind, such for example as leather Scraps, straw board, cement, or what not, so that the filling together With the longitudinal margi'nal portion 5 of the heel are, to all intents and purposes, the same as they were Originally, so far as the function that portion of the sole is to perform. After the eavity has been thus filled, the lip 1 is cemented, down, or otherwise Secured over the filled cavity and marginal portion so that from the top the appearance of the sole remains substantially as it was Originally. The main body of the heel is Secured to the heel ortion in the usual manner beneath the fil ing and marginal portion 5, and the bottom lift such as removed from the sole or some other of equal quality is then Secured to the bottom of the heel and the heel is finished.

In the modification, the only difference is that the heel is cut with a slight bevel recess in the main form of the invention it is cut straight.

It is obvious that this invention finds its greatest utility where the sole blank is comparatively thick.

It will be observed that by this invention a portion of material which Would otherwise be practically wasted is in this manner utilized, while the full value of the sole is neither impared, nor marred in appearance. Furthermore, it will be observed that the outer margin of the finished sole including the heel portion remains to all intents and purposes precisely the same as if it had not undergone this transformation, peculiar to this process as neither the original thickness nor quality of the outer edge of the heel portion of the sol leather has been altered, the only portion removed being that taken from the cavity which is filled and ultimately oovered by the heel itself. Thus there is a 'saving of valuable material, and consequently a reduction in the cost. I

It may be necessary to paste a thin piece of material over the top of the heel portion of the sole to make a neater looking job as shown at 9 in Fg. 5.

Slight additional changes may, of course, be resorted to in the form and arrangernent of the several parts described, Without departing from the spirit and scope of my invention, and hence I do not Wish to limit myself to the exact Construction, herein set forth, but

Having fully described my invention, What `I claim as new and desire to secure by Letters Patent, is

l. An outer sole for boots and shoes, the heel portion of Which is split to form an integral lip, and the thicker portion having a heel lift cut therefron, the lip being adapted to cover the cavity thus formed.

2. An outer sole for boots and shoes having the heel portion split and having a cavity formed in the thicker portion by the cutting and removal therefrom of a heel lift,

In testimony Whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL H. SHILLABER.
